Hi Phil,
Under the pressure tab, you can convert kg/cm2 to lb/ft2.
Since kg/cm2 is g/m2, multiply the result by 16, and you have oz/ft2
I have an Excel spreadsheet that I can post as well that does a couple
of other things for electric fliers and wing loading.

The question I meant to ask was how to use the little conversion
program to do conversions that were not already on the menu. Someone
was kind enough to respond off list so I'll repeat the information here;
Click on "options" at the top of the window, then click on
"preferences". Then click on "custom". You type the conversion into
that window and then when you click on "custom" on the regular menu
you will see the custom conversions that you have typed in.
The conversions that you need for the question that Rich asked about are;
1 gram per decimeter squared = .327123 ounces per foot squared
1 decimeter squared = 15.50003 inches squared
I already knew how to do the conversions manually as evidenced by my
earlier post reprinted below:

At soaringusa.com, the ThermicXL is listed with 81.7 dm squares and
36.7 grams/ dm square.
Can someone tell me what that would be in square feet .
81.7 square decimeters = 1266 square inches.
36.7 grams per square decimeter = 12.0 ounces per square foot.
Eventually I want to figure the wing loading at different all up
weights .
1266 square inches = 8.79 square feet.
12 ounces per square foot multiplied by 8.79 square feet = 105 ounces.
The manufacturer must be assuming 105 ounces to get their listed wing
loading.
To check wing loadings for different weights you just need to divide your
weight in ounces by 8.79 square feet to get your wing loading in
ounces per
square foot.
